Association of glutathione S-transferase omega polymorphism and spinocerebellar ataxia type 2

Farrerol attenuates cisplatin-induced nephrotoxicity by inhibiting the reactive oxygen species-mediated oxidation, inflammation, and apoptotic signaling pathways

showed a decrease in sputum NE activity, neutrophil count, levels of pro-inflammatory cytokines (IL- 8, IL-1beta, TNF- alpha and LTB4) and the numbers of Pseudomonas aeruginosa after 2 and 4 weeks aerosolized A1AT treatment

In the case of glutathione IV therapy side effects, some patients worry that direct injection into the bloodstream could have an off-target impact

demonstrated a favorable response to A1AT in patients with advanced-stage gut SR-GVHD, including those who had previously failed other treatments for SR-GVHD (19)
